SERVICE-BOX FOR WATEFi--CLOSETS SPECIFICATION forming part of LettersPatent. No. 381,911, dated May 1, 1888.

Application filed April 28, 1887. Serial No. 236,429. (No model.)

To all whom it may concern.-

Be it known that I, JAMES CRAWFORD, of Cambridge, in the county ofMiddlesex and State of Massachusetts, a citizen of the United States,have invented a new and useful Improvementin Service-Boxes forWater-Closets, of which the following is a full, clear, and exactdescription, reference beihg had to the accompanying drawings, forming apart of this specification, in explaining its nature.

The object of the invention is to provide a simple and efficient meansfor providing the closet with a copious supply of water, and one thatshall continue after the opening of the valve and the release of thelever operating it.

The invention comprises a service-box having a discharge-outletcontrolled by a valve operated in part by a Weight or balance and 1npart by the float which governs the cock of the water feed-pipe.

In the drawings, Figure l is a view in vertical section of theservice-box, showing the position of the parts when the valve is closed.Fig. 2 is a vertical section showing the position of the parts when thevalve is open. Fig. 3 is a detail view of a part of the floatarm andvalve-rod.

Referring to the drawings, A represents the service-box. ais thewater-supply pipe; a, a cock, which is of ordinary construction, andwhich is opened and closed in the ordinary way by the float a which isconnected with the cock by thelong arm a B is a casting forming theframe of the valve and also the passage through which the water escapesfrom the service-box. It extends through the bottom of the box and has acoupling end, I), upon the under side thereof. It has also an inclinedopening, which is adapted to be controlled or closed by the clappervalveO. This valveis pivoted at c to the casing B of the valve, and its arm ais connected with the operating-lever c by a rod, 0 which passes througha hole, a, in the inner end of the lever. This rod is free to move insaid hole to any degree or extent, limited only by the adjustable blockor stop 0", which is fastened to the rod by a screw, 0". Theclapper-valve C also has secured to it near the fulcrum or pivotal point0 an arm or rod, 0,

extending, when the valve is closed, upward sufficiently out of theperpendicular tocause the weight 0 which it carries at its upper end,and which preferably is of lead, to keep the valve closed. The rod 0also has a stop, d, which is adjustable thereon, and which is securedthereto at any place thereon by a screw, (1. The valve-rod is alsoconnected with the arma of the float a by the loop or connection 01 sothat the float-arm is free to move on the valve-rod, but is held theretoin a manner to bring it in contact with the stop d, as will hereinafterappear.

In operation, the lever 0 having been moved to open the clapper-valve O,is released in the ordinary way. The valve 0, however, instead ofclosing immediately, remains open, being held open by thecounterbalancingweight 0 which then assumes the position represented inFig. 2, and the lever 0 being free to move upon the valve-rod c, returnsto its original position. The valve 0 remains open to permit the waterto escape from the servicebox until the float a has fallen sufficientlyto bring its rod into contact with the stop d, when the valve 0 iscaused by the weight of the float as the water is gradually drawn off tobe closed or partly closed, the weight 0 after it has passed aperpendicular position,serving to assist in closing the valve. Thefloat-lever is then lifted in the usual way by the inflow of water intothe service-box from the supplypipe a and rides upward upon the valvestem or rod 0 without, however, moving the same, and until it operatesto close the inlet-cock a. The downward movement of the clapper-valve toclose the outlet of the box of course brings the stop 0 upon the upperend of the valverod into operative position with the lever 0 By makingthe stop (1 adjustable upon the valve-rod c the valve 0 may be set orcaused to operate after the escape of any given quantity of water fromthe box.

I do not confine myself to the especial form of valve herein shown anddescribed.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- 1. In a service-box forwater-closets, the combination, with the outlet'passage valve 0, havingthe inclined upwardly-extending arm provided with thecounterbalancing-weight arranged above the pivot of the valve to holdthe latter open or closed, of the operating-1ever 0, a rod whichconnects the said lever with the said valve and which is provided with astop, an arm which controls theinlet cock and which is arranged toengage the said stop, and a float for operating said arm, whereby whentheoperating-lever is actuated the dischargevalve will be opened andheld open by its counterbalancing-weight until the float-arm falls farenough to engage the stop on the conmeeting-rod, when the said valvewill be automatically closed, substantially as set forth.

2. In a service-box for water-closets, the combination, with the valve0, for controlling the outlet-passage from the box, the said valvehaving the arm 0, provided with the counter- :5 balancing-weight c ofthe operating-lever c, the connecting-rod 0 having a loose connectionwith the said lever c and provided with the adjustable stop (I, the arma for controlling the inlet-cock, having the loop at to engage 20 saidstop, and the float a attached to said arm, to operate substantially asset forth.
